IMPROVEMENT IN SHUTTLE-SPINDLE.

a 1 0 all whom it may concern;

Be it khown that we, HENRY WHEELER and OLIVER H. REED, both of Lowell,in the county of t-ion of a portion of a common loom-shuttle,-with our.

improvements applied thereto. I

Figure 3, a sectional elevation of a detached spindle.

This invention relates to that kind of shuttlespindles which haveslender springs arranged on theupper sides, and which springs are pushedoutward and caused to bow upward or press against the yarn and hold thecop on the spindle.

This invention has for its object, not only to simplify the process ofactuating'tbe spring, but to simplify and cheapen the mechanism by whichthe spring is actuated or forcedoutward.

\Ve apply the spring a to the point of the spindle, and its rear end inan aperture'in the forward side of the head in' the usual way, but therear .end of the spring is enlarged and bevelled or mitred on its upperside, as shown, and this bevelled enlargement works freely in theaperture.

In the upper side of the spindle-head b, and near the forward sideof it,we form a second aperture, at 'or nearly at a rightangle with, andopening into that first named.

In the last-named or vertical aperture formed intheupper side of thespindle-head, we insert an actuatiugpin, c, the lower orinner end ofwhich is bevelled. or mitred to fit. or nearly fit the bevelled end ofthe spring.

The upper end of the pin 0 rises a little above the top of thespindle-head, and convenient for-being pressed downward to force thespring outward.

When this spindle isapplied tothe shuttle, the top end of the pin 0comes directly under the forward or inner end of the top'spring-plate d,and this presses the pin downward and actuates the spring or throws itup in the form of a how, all as clearly shown in fig.1, or as near thisform as the cop of yarn will admit.

I When the cop is placed on the spindle, the latter is thrown upward toaposit-ion shown in fig. 2, and this carries the top 'of thespindie-head, and the top end. of the pin over and backward to beneaththe top plate, liberates the pin from the pressing action of theplate-spring, and allows the spring ato throw the pin upwardpaud thespring to resume its form and position on the topof the spindle; the copis then pushed on to the spindle, and the latter thrown downward to theposition shown in fig. 1. This brings the top end of the pin under theend of the top spring 11, and actnates thepin, and the spring a forcesthe-Jar ter outward and holds the cop on the spindle.

The actuating-pin 0 should be applied forward of the pivot g, on whichthe spindle swings, otherwise the pressure of the top plate-spring wouldthrow the point of the spindle upward, and bring the cop partly abovethe top of the shuttle, and' prevent the latter -passing through theweb.

Vhen nearly all the yarn has run otf from the spindle, the rear portionof the spring a is liable to rise, and allow the few remaining yards toslip ed and become waste.

To obviate this, we sometimes term the spring thinner and weaker, atabout the point f. This allows the forward portion of the spring to risefirst, and this rise at f retains the yarn until all of it runs offthrough the eye ofthe shuttle and is woveninto the web, which is anobject of some importance.

we do not claim a spring applied to the point of the shuttle-spindle,with its rear end passing into the head, as this is an old device; but

What we do claim. and desire to secure by Letters Patent, is-

The actuating-pin c, constructed as described. with a bevelled lowerend, and applied to the head b, -forward of the pivot g, in combinationwith the spring a, 'provided with the bevelled end, and with the topplate 11, in the manner and'for the purpose set forth.
